MINNEAPOLIS -- A tumultuous season for Minnesota Twins catcher Joe Mauer has come to an abrupt halt.

The team announced prior to Friday's game against the Cleveland Indians that Mauer has been shut down for the remaining 14 games due to pneumonia.

"On September 2nd he was diagnosed with an upper respiratory infection, and despite medication the symptoms have not resolved," said head athletic trainer Rick McWane. "In Kansas City (earlier this week), he complained of a persistent cough.

"(Thursday) he was sent to the Mayo Clinic and was diagnosed with mild pneumonia."

McWane added that Mauer was told to take medication and rest for two weeks.

Mauer missed two games earlier in the month with the aforementioned upper respiratory issues, and he also spent time in the hospital in mid-April with a viral infection while simultaneously being sidelined with bilateral leg weakness.

All in all, Mauer played in only 82 games this season -- 52 at catcher -- and his .287 batting average is the lowest of any season in his eight-year career. Mauer also set career-low totals in home runs (3), on-base percentage (.360) and slugging percentage (.368).

"He's not very happy," manager Ron Gardenhire said. "He's pretty upset about it. He's going to have to do what the doctors say, we all know those things, and take care of himself physically, absolutely. But he really, really is not happy about this situation. He wants to be out there. He wants to be here with the guys, so he's pretty upset."
